Synthesis, characterization, and photocatalytic activities of novel bentonite-supported BiOCl-ZnO heterojunction (BiOCl-ZnO-Bentonite) under UV light
(Wiley, 2018)
Herein, we report the synthesis of a new composite catalyst immobilized on bentonite surface (BiOCl-ZnO-Bent). The samples were characterized using Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), ...
STRUCTURE, OPTICAL AND PHOTOCATALYTIC PROPERTIES OF ZNO/CUO/BENTONITE NANOCOMPOSITES IN THE OXIDATION OF 2,6-DICHLOROPHENOL
(Springer, 2017)
ZnO/CuO/bentonite (Bent) ternary nanocomposites were obtained by coprecipitation and characterized using FTIR spectroscopy, scanning electron microscopy (SEM), and X-ray diffraction (XRD). The SEM images indicate that the ...
Double Effect Electron Transfer System in the AgBr/ZnO Composite with Enhanced Photocatalytic Degradation Performance against 3-Chlorophenol under Visible Light Irradiation
(Wiley, 2018)
Visible light-driven novel and highly efficient AgBr/ZnO photocatalysts were synthesized by a facile precipitation and dehydration methods. The synthesized samples were characterized using scanning electron microscope ...
Triterpene glycosides from the roots of Astragalus flavescens
(Amer Chemical Soc, 2008)
Six new triterpene saponins, 3-O-alpha-L-rhamnopyranosyl-(1 -> 2)-beta-D-Xylopyranosyl-(1 -> 2)-beta-D-glucuronopyranosyl-21-epi-kudzusapogenol A (1), 3-O-alpha-L-rhamnopyranosyl-(1 -> 2)-beta-D-glucopyranosyl-(1 -> ...
Synthesis and characterization of visible-light-driven La-doped p-n BiOCl/ZnO heterojunction photocatalyst: mechanism investigation of 3-Cholorophenol degradation
(Springer Science and Business Media B.V., 2021)
Herein, ZnO, BiOCl, lantanium-doped ZnO, BiOCl and BiOCl/ZnO catalysts were prepared using facile precipitation. Samples were characterized by scanning electron microscopy (SEM–EDS), Brunauer–Emmet–Teller (BET), UV–vis ...
Chionaeosides A-D, triterpene saponins from Paronychia chionaea
(Amer Chemical Soc, 2007)
Four new triterpenoid saponins, chionaeosides A-D (1-4) were isolated from the roots of Paronychia chionaea. On the basis of their spectroscopic data, the structures of the new saponins were established as 3-o-alpha-L-ar ...
Age-related changes in tissue and plasma zinc levels: Modulation by exogenously administered melatonin
(Taylor & Francis Inc, 2008)
Melatonin (MEL) is synthesized mainly in the pineal gland and derived from 5-hydroxytryptophan (5-HTP). Zinc (Zn) is one of the most important trace elements in the body. Zn and MEL levels are changed with aging. The aim ...
